An engine comprising an isothermal air compressor ( 1 ) into which liquid is sprayed as the air is compressed. A combustion chamber ( 4 ) receives and expands the compressed air from which the liquid has been removed, to generate power. A precompressor ( 21, 27 ) compresses the air upstream of the isothermal compressor. The compressed air from the isothermal compressor receives heat from the exhaust gas from the combustion chamber in a primary heat exchanger ( 3 ). A secondary heat exchanger ( 31, 45 ) transfers heat recovered from a part of the engine to the compressed air from the isothermal compressor ( 1 ) upstream of the primary heat exchanger ( 3 ). |
